Invalid argument - unknown wkt,this is the exception which i got
hello ,Adam.thank you for your answer,how nice of you.these days I have try to solve my problem,but it's still some problem in my project.
First,the project can be runing ,and the window can show out,but there is nothing be drawed in the window which is all blank.
I FEEL better because it's not be throw out the exception i encounter before.
Second,the shapefiles i downdoad can be draw in the Arcmap(desktop vision 10.1),there is a lot of line which represents the road in the Arcmap.I USE the analysisMap function,then it tells me that the map don't have the Spatial Reference or index（in chinese both are same meaning,my Arcmap are chinese vision）,which it's a serious warning，and I double-click it ,and then the map was added the Spatial Reference.And the file was added more three new files which is sbn. sbx. and shp.xml.but the window are still all blank.
the render code are followed： UniqueValueRenderer uvRenderer = new UniqueValueRenderer(
new SimpleLineSymbol(Color.RED, 1), "name");
featureLayer.setRenderer(uvRenderer);
jMap.getLayers().add(featureLayer);
any error in my code?
I KNOW the UniqueValueRenderer class' second parameter is column Header from the dbf.file which you can open it to see it .the sample code is also use the column Header to be the second parameter,and the sample can be drawed.BUT in my projet use it the same way,but it just can't be drawed,
Third,you tell me to re-creat the prj,file by Arcmap.I wish i can handle it ,but the function to define the projection have some problems.
when I choose my shapefile,it tell that my date set is not exist or not supported.
I AM JUST CONFUSED.IF you know something that can help,please let me know.
california-latest-free-roads.shp.rar - Google Drive
this is the shapefiles in clonddisk lisk.
this is the code text
and this is my project.ArcGIS_runtime_java's vision is 10.2.4.I BUILD the project by the steps by the official guide tell me.
Hi,
The shapefile is not corrupted (Please remove the first dot (.) in the file name, there should be gisosm_roads_free_1 instead of gis.osm_roads_free_1) and the code is almost perfect - you should not use unique value renderer in this case, since there are too many values, which you do not actually add. Also, the rendering time of the whole shapefile on my machine is about 2 minutes - far too long.
When I created a subset of shapefile the rendering is almost instantaneous. I suggest you do not display the whole shapefile, you can use Local Tiled Layer for display purposes.
Here is the valid code of the createMap() function:
private JMap createMap() {
// map
JMap jMap = new JMap();
ArcGISTiledMapServiceLayer basemap = new ArcGISTiledMapServiceLayer(BASEMAP_URL);
basemap.setOpacity(0.5f);
jMap.getLayers().add(basemap);
// Add shapefile
try {
shapefileTable = new ShapefileFeatureTable("C:\\tmp\\gisosm_roads_free_1.shp");
featureLayer = new FeatureLayer(shapefileTable);
// create a renderer
SimpleRenderer simpleRend = new SimpleRenderer(new SimpleLineSymbol(Color.RED, 2.0f, SimpleLineSymbol.Style.SOLID));
// set renderer
featureLayer.setRenderer(simpleRend);
jMap.getLayers().add(featureLayer);
} catch (FileNotFoundException e) {
JOptionPane.showMessageDialog(jMap,
wrap(e.getLocalizedMessage()), "",JOptionPane.ERROR_MESSAGE);
}
return jMap;
}
Hope this helps,
Adam
